NATURE OF RELEASE: Incorrect routing of rocker oil feed pipe. MODELS AFFECTED: All Late moderl Commando with flexible rocker pipe. PARTS AFFECTED: Flexible Rocker Feed Pipe DISTRIBUTION: Worldwide- Trade Only EXPLANATION: On the introduction of the flexible rocker feed pipe, the overall length of the pipehas been increased. Some 100 machines are known to have routed incorrectly so that left the factory with the pipe fretting could occur between the oil pipe and banjo and the right side of the rocker box. Potentially under these conditions the pipe may fracture after a period of use.   ACTION: Examine all the machines with the flexible rocker oil feed pipe. The pipe should pass from the take off banjo on the rear of the timing cover, through the gearbox aperture in the rear engine plate, then between the rear engine plates, and between the carburettor manifolds to the right side of the rocker box. Be careful to give clearance between the pipe and the rocker spindle end cap bolts at this point. The branch pipe to the left side passes over the top of the rocker box forward of the cylinder steady. Make sure that the pipe does not come into contact with the head steady.
